i'll bet you processor speed is set wrong
the way it works is this
bus speeds
33, 66, 100, 133
multipliers
x2, x2.5, x3.0, x3.5 ......
dont know if your machine has jumpers on the motherboard or if it has it in the bios
but lets say you have a 133mhz bus speed on your motherboard and you processor is 733mhz
to get this figure you must multiply 133 x 5.5 = ~733
or what ever but that is the math to use , and from your posts im sure youll get it from there
